摘要
A novel complex Cu(PPh3)2(acac) 1 (PPh3 = triphenylphosphine, acac = acetylacetone) was obtained by a solution reaction and structurally characterized by X-ray diffraction. The crystal belongs to monoclinic, space group P21/n with a = 13.7361(8), b = 12.8204(7), c = 19.7638(13)A, β = 95.946(2)^o, C41H37CuO2P2, Mr= 687.19, V = 3461.7(4)A3, Z = 4, Dc = 1.319 g/cm^3, S = 1.067,μ(MoKa) = 0.758 mm^-l, F(000) = 1432, R = 0.0403 and wR = 0.0990. Complex 1 is characterized by an isolated structure. X-ray structure analysis of I shows that acac behaves as a chelating ligand and PPh3 coordinates as a monodentate ligand to the Cu(I) atoms. Photoluminescent investigation reveals that the title complex displays a strong green-light emission.
